CAN 0B CONTAINER.

Application mea July 1s,

This invention relates to containers such as cans, pails or the likewhich may be adapted for general use but which are particularl intended for receiving and shipping hqui or mixed paint or other material having highly volatile ingredientsor of a volatlle character. For general commercial purposes. it is necessary or desirable to provide paint cans of the larger sizes with covers which may be applied mechanically and which will make substantially airtight closures. Thesel 1 tions and maybe'said broadly to provi e an improved can and closure. Other objects Aare to provide a can having a novel form of bead which is adapted to be en aged by the cover holding means and to ho d the same more securely than will the ordina-ry bead; to' provide acan having a bead with an angular or flat portion for receiving the cover holding lugs; and in general to provide such f an improved arrangement as will be described more fully hereinafter.

In the accompanying drawings illustrating this invention;

Figure 1 is a side view of a complete can embodying this invention; v

Figure 2 is an enlarged sectional detail of the upper portion of the can and cover;

Figure 3 is a view similar to Figure 2 showing a modied form of construction; and

Figure ll is another similar viewshowing a further modification.

The container or can 5 may be of any desired shape but is illustrated as being substantially cylindrical and as having one or more annular ribs or projections 6. The upper ends of such cans are commonl formed over round bead wires thereby forming a substantially round rolled edge or bead around the upper end of the can. When the ordinary cover is applied to' such cans, the fastening lugs or lips around the outer edge of 192s. serial no. miasaxi.A

the cover are bent under such rolled edge or bead in order to hold the cover in position. I have found, however, that on account of the curved surface and on account of the tendensring after being bent into position it is ilicult to make a tight closure with suchv covers and even if the covers are well fastened in the first instance they are apt to become loose on account of the lips or rojections sliding over the bead instead o holding securely to the same.

lIn order to avoid such objections -and to provide a more positive holding arrangement, I provide a beadwire or ring?? as shown in Figure 2 which is flat on the lower side and curved on the upper side andwhich for convenience may be designated as a half-round wire. The upper end- 8 of the can is formed or rolled over this ring with the extreme outer portion bent inwardly across the bottom of the ring so as to make a flat surface 9 at about right angles to the outer wall of the can, there being a comparatively sharp angle or corner 10 formed where the end of the can is bent inwardly over the outer edge of the ring. It will be seen that instead of a round surface, this bead 11 provides an annular, flat engaging port-ion which is adapted to coact with the cover fastening means.

The cover 12 preferably fits closely within 'the body of the can and has an annular upwardly and outwardly extending rolled portion 13 which lits over the bead and preferably engages closely therewith. When the can is to be used for particularly volatile material or when it is to be hermetically sealed, a gasketle formed of rubber tubing or the like may be inserted between the cover and bead 11 as shown in Figure 2. The cover is rovided with a plurality of holding lips or ugs 15 which are'preferably formed integrally with the outwardly rolled portion 13 and extend down below the bead 11. When the can is to be closed, the cover is ressed down tightl against the top and the ugs or lips 15 are t en bent inwardly under the at cy of the cover holding means to yield 'or 60 surface 9 of the bead 11 to securely fasten the cover in position. It will be seen that these lips or holding portions of the cover ma be bent sharply around the angle 10 w ich greatly increases their holding capacity and which will prevent the cover from becoming loosened until these lips are again bent out of fastening position.

In the modified form of construction shown in Figure 3, a can 5 is provided at the upper end with a bead wire 16 of square or rectangular cross section which will provide a flat lower engaging surface 17 for the bead 18. The cover 19 is constructed substantially the sameas above described and has lugs or lips 20 which are adapted to be bent under the flat lower surface of the bead in order to hold the cover securely in position.

In lthe further modification shown in Figure 4, the can 5 is shown with a bead 2l which is formed over a bead wire or ring 22 of substantially triangular cross section but having a flat lower surface whereby the lower portion of the bead will be at approximately y right angles to the side of the can. The cover 23 has projections or lips 24 which engage with the lower surface of the bead as above described and the outer portion of the cover is rolled to it the bead.l In this instance the angle 25 at the lower outer ortion ofthe bead forms of constructions, and therefore I do not wish tokkbe limited to the exact shape or arrangement herein shown and described except as s eciied in the following claims in which I c aim:

l. A`can having a bead with a iat 'lower surface and a cover for said can having engaging portions adapted to be bent inwardly under the outer corner of the bead to engage with the lat lower surface, said engaging portions being bent to form sharp corners where they engage with the outer lower corner of the bead. s

2. A can having an outwardly projecting bead having a iat lower surface at an acute angle tothe outer surface thereof, a cover having a portion fitting over said bead and having lugs for engagement therewith, said lugs being bent inwardly at an abrupt angle under the correspondingly acute angle at the outer edge of the bead to engage with the flat lower surface. l 3. The combination with a can having a bead formed over a ring and havin an acute angle at the lower outer portion tereof, of a cover having engaging portions adapted to be bent over said angle to hold the cover in position, said angle serving as a ulcrum over which the engaging portions may be readily bent and which w1ll tend to securely on the can.
